Bromoacetic acid is the chemical compound with the formula CH2BrCO2H. This colorless solid is a relatively strong alkylating agent. Bromoacetic acid and its esters are widely used building blocks in organic synthesis, for example in pharmaceutical chemistry.
The compound is prepared by bromination of acetic acid.[1]
- CH3CO2H + Br2 → CH2BrCO2H + HBr
The compound has a refractive index of 1.4804 (50 °C, D).
